T 0 all whom it may concern:

Be it lmown that I, MALCOLM BIK R, a citizen of the United States, and a residen of Dover, in the county of Morris and State 5 of New'Jersey, have invented certain new an useful Improvements in Pile-Pulling Apparatus, ofwhich the renewi is a speci- My invention relates .to devices for pull- .10 ing piling, particularly sheet piling, by means of power apparatus. The device to which this invention appertains is designed to be used invconjunotion' withla pneumatic hammer p-i le pullin rig tor the purpose of Li: starting the pine-1'1 breaking the 101 1 between the piling to be w t drawn'and the adj aeent piling; which the pilinglinay be comp-letely' removed by the pile pulling rig without severe strain on the derrick.

It is the object of the invention to provide a well constructed, tcompact, simple, inexpensive and efficacious' pile pulling attachment which may bereadily transported and placed in position for use.

nother object of the invention is the provision of a strongly built device which cooperate witha power hammer to start firmly embedded iling;

With the foregoing and other objects 111 30 view .whichwill' become apparent as'the description ro eeds, my invention resides in the combination and arrangement of parts and in thedetails of construction described in the specification and particularly pointed out in the ap ended claims, it be ng undertood that I I o not'limi myself the pre cise embodiment of the invention herein disclosed, and changes can be made within the scope of what .iS claimed withoutdeparting from the spirit of the invention.

In the accompanying drawings Figure 1 is an elevation of the device in position for use in connection with a pile pulling rig. I i

Figure 2 is a plan view of the attachment showing the arrangement of bolts and spreaders, theattach'ed cables and the piston rod being in section, and n ig. 3 is an enlarged el vatio rtly in :secti n, of the-hamme and hydraulic puller.

Similar refe ence nu rals. refer to similar parts throughontthe several views.

The numeral 10 designates the ma n ing of a well known ifiOIHi of pneumatic pulling operat on. v

The support lever arm as shown ,com-

hammer, the enlargement? containing the usual valves and air ports. for the control and operation of the hammer, The casing is supported by a able. 8 passing under; the casing and lo ps ove a hook] uspende from'a derrick arm by cable 5. A cabl sling 5, in this instance, oomprising three cables, passes over the filling block 'b'ew n th guides the ends Offll? vsling ing f s ed o the tiling by he c mp 'The' retaining ring -1 passes aroundth suppor ing cable an the cable inah lding' them in position and at the same time serving to keep the hammer casing upright, there being no other-means usedf for holding the parts together. This retaining ring 1 rests on the anvil blo k ll fits int o undercut groove of the filling block 4: and rides inthe undercut portions of theguides 3 3. V .17'

At the lower endof the casing lOis a "hydraulic cylinder in which is" 'a piston 19, fluid passing into the cylinder above the piston by means of-the connection 18.. The piston rod 17 is attached to the piston 19 and is pivotally attached at the lower: end 16 to the support lever arm 15 fuloru ined as at 14: to the post 13 which has an inverted U-shaped end 12 pressing down on the" em bedded piling. The other end 21 of the support lever arm 15 is anchored to'the'embedded pilin by thecables 22 23 j i Aslack ca le 24; is attachedfrom the easing to the anchored end of the lever arm and supports the free endof this part o-f-the mechanism when it is-not in use as, for eX-' ample,'when the pile has been started, the

anchoring cables22 23v detached, the pile pulling rigis in action cornpleti'ng the prises two plates 25, 26, having the spacers 27 27 set between them, .allowingthe' insertion of'the T get 13 between the plates and permitting he lever torock rreeiy on-the pivot pinlc. In use the entire apparatus is placed in position as shown Figure 1. Fluid is admitted above the piston'19'by oonnection18 and there is a reaction between the ings-19 and the cylinder The piston cannot move downward materially as it I is anchored by the ables 2 2 ns quently-th a s m re u wa d nsth ab e $11 2 5 t u er g a t y and f reete P1 130 the clamp 2 and starting the pileto 'which thence by the clamp 2 to this clamp is attached, the adjacent piiing being held down by the pressure of the post '13. .The derrick arm takes up the slack or the cable 8. v

The hammer may be used to augment the efl'ect of the hydraulic device to start and break the joints, after which the hydraulic device may be released'and the hammer used ,to complete the withdrawal of the pile, the

action of'the hammer on the anvil block 11 being transmitted to the cable sling 5 and the pile. Thus the pile may be completely withdrawnand laid aside," the flexibility of'the cable sling per- ,m'itting this to be done before detaching the clam In explanationof the use of this auxiliary starting devlce it maybe said that in service,

'sheet piling is very often under a severe transverse strain from hydraulic pressure from the outside and that under this'infiuence the joints between the piling become filled with sand and silt very tightly packed.

In addition, to this there are times when the sheet piling is used as a form and concrete is poured directly into it. In either of these cases it is very difficult to break the joints between'the piling but after the pile is once ,moved, the resistance to pulling is considerably reduced. The apparatus to which this a piston in operative relation therewith, and

having relative motion thereto, means for anchoring said piston against movement,

. means to supply fiuid'under pressure to said der and a piston cylinder, and an .operative connection between said cylinder and a pile whereby the motion of said cylinder is transmitted through "said connection to said pile.
